ILS is right, they're not worth the money. I would shop around a bit more, there are better speakers for the money. And I can't stress enough that you should never get it 'professionally' installed, especially from Strathfield. They do bodgy jobs, they didn't do a good job on Rmyers' install. I would do it myself, it's not hard.
Whatever you do don't buy Sony. They're stuff is crap. I haven't heard anything good about them. Kenwood is good, so is Pioneer, Audioline stuff is reasonable, nothing special, just average but the prices are LOW... Blaupunkt is good but can be a bit pricey... I especially like Kenwood 7x10s, brilliant speakers in my opinion, and they're not too pricey.
If your after some speakers that will sound good and not break the bank, one brand that comes to mind is Philips. You could pick up a set of their 2 or 3 way 6.5" and 3 way 6x9's plus installation for around $400. Professional installation should cost around $80 for the 6x9's and about $60 for the 6.5". They also have some nice 8" 3-ways that can be a good alternative to the 6x9's. In my opinion, Philips speakers are often overlooked but they really do sound good (I've installed quite a few sets). They have a balanced sound and can also handle a bit of bass.
If you shop around there will be quite a few brands that will have speakers in your price bracket. There are always the usual Pioneer, Kenwood and Sony. Also look at the more 'exclusive' brands that often have a bit more to offer. To give you an idea of some brands..... Infinity, MTX, Alpine, Rockford Fosgate, Orion, Cerwin Vega and Clarion.
